Dynamic reconfiguration design of signal processing platform based on Ethernet

Abstract： The signal processing platform usually uses FPGA+DSP+ARM architecture to achieve specific signal processing functions, with the development of signal processing technology, more and more engineering applications require signal processing platform to have dynamic reconfiguration capacity. This paper introduced a design of dynamic reconfiguration based on Ethernet, which can realized the dynamic update of multiple FPGA and DSP on the signal processing platform. At the same time, it did not need the configuration memory in previous design, and the configuration time is short, which can meet the application requirements in various scenarios. The design has been verified in many practical projects, and has achieved ideal experimental results, with high portability and scalability.
